Which coin can be used for real day-to-day payment these days?
Oviously btc is more accepted than any other coin.but after btc i think eth,ltc,waves,doge, dash will be used in real life usage.
Nothing beats bitcoin yet since thefe are lots of feature it have, then in terns of alts it maybe depends on the alt project on what ICO it came from some ICO were for personal use and sone for applications.
